Dynamically Populate Batch Number Select Based on Product Selection in Filament

Hi everyone,👋

I’m trying to populate a Select field for batch_number based on the selected product_id in Filament. I want the batch_number select to be dynamically updated after a product is chosen. Here’s the code I’m working with:
Select::make('product_id')
    ->live()
    ->translateLabel()
    ->options(function(){
        return Product::pluck('name','id');
    })
    ->required()
    ->afterStateUpdated(function(string $state, Set $set){
        // Get the selected product
        $product = ProductService::fromId($state);
        // Generate options for the batch_number select
        $optionsForBatchNumberSelect = $product->getWarehouses()->pluck('batch_number','id');

        // Set the batch_number select with the generated options
        $set('batch_number', $optionsForBatchNumberSelect->toArray());
    }),

Select::make('batch_number')
    ->live();

The issue is that the batch_number select isn't being populated after the product is selected. What am I missing or doing wrong? How can I make the batch_number field update dynamically based on the product selection?

this is the value of the variable $optionsForBatchNumberSelect->toArray():
array:3 [▼ // app/Filament/Resources/WarehouseTransferResource.php:85
  1 => "499104"
  13 => "499104"
  14 => "221"
]
